Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed January 6, 1912. Serial No. 669,740.

To all whom it may concern:

Be it known that I, FRANK W. MERRICK, a

citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Lasting-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention resides in novel devices for feeding a continuous length of wire, driving the leading portion thereof to constitute a fastening, cutting off, completing, and setting such fastening. The said devices are useful, either as a whole or in part, for purposes in general, but I contemplate more especially the employment of the same in the manufacture of boots and shoes, and particularly in lasting.

The invention is shown herein embodied in a hand-operated machine or implement which has been contrived for the purpose of securing the upper of a shoe in place in the lasting operation by means of preliminary fastenings. A special aim in this connection has been to provide for the application of fastenings of a character such as not to interfere with the subsequent operation of sewing, and hence not requiring to be extracted or withdrawn to permit of such operation being performed. In other words, to provide for the application of preliminary fastenings of a character enabling them to be allowed to remain in place, without extraction or withdrawal as in the case of the tacks employed atpresent for lasting purposes. The idea is to employ a fine soft wire that will not occasion injury to either the awl or the needle of the sewing machine in case a fastening should be encountered thereby. However, it is to be understood that the features of my invention are not restricted in all cases to use in lasting, or with wire of the character mentioned.

The said machine or implement as herein illustrated comprises jaws which close upon the upper and the lip or flange of the insole, or upon the upper and the margin of the sole in certain kinds of shoes, and draw the upper snugly around the last and into proximity to the shoulder of the insole or the surface of the sole; a guide in connection with one of such jaws for the continuous wire of which the fastenings are formed; a tool which feeds such Wire, drives the leading end thereof through the upper and the material of the insole or sole at the point where they are held in the pinch of the said jaws, clenches the said end against the other jaw, cuts the wire to sever the inserted fastening therefrom and leave a standing end on such fastening, bends over the said standing end in a predetermined path, and cooperates with the opposite jaw in finally setting the fastening.

The invention is not restricted to the particular form of embodiment herein shown and described. Nor are the features thereof restricted in all cases to use in hand-operated machines, implements, or tools, inasmuch as they may be embodied in automatic machines.

In the drawings, Figure 1 is a side elevation of the said machine with the jaws thereof open or separated. Fig. 2 is a view of the same in vertical section, with portions of a last and a shoe, the jaws being open. Fig. 3 is a sectional view showing the jaws closed upon the upper and the flange or lip of the insole of the said shoe, and the tool engaged with the wire as at the beginning of the feeding and driving operation. Fig. 4 is a sectional view showing the feeding and driving operation consummated, the leading end of the inserted fastening clenched, and the cutting completed. Fig. 5 is a sectional detail illustrating the operation of bending the standing end of the inserted fastening over in a predetermined path. Fig. 6 is a sectional view on a larger scale than the preceding views, illustrating the setting operation as completed. Figs. 7, 8 and 9 are detail views of the aw 2, also on large scale.

, Having reference to the drawings, the aws are marked 1 and 2, respectively. The jaw 1 is shaped at its working end to enter fully home into the angle between the main portion of the insole a, Figs. 2, 3, etc., and its outstanding lip or flange (2'. The said working end is provided with the anvil 1 which is properly concaved, as shown in Figs. 4, 5 and 6, to deflect the leading end of the wire around and back toward the material through which it has been driven, in order to clench such end. The said working end is provided with the small projecting ll 1", located at one end of the concavity o the anvil. When the jaws are closed together upon the material clasped between them, this lip penetrates the material and approaches close to the jaw 2, as shown most clearly in Fig. 6. Its oflice is to guide the end of the wire with certainty into the concavity of the anvil, and by being carried into close proximity to jaw 2 before the wire is forced through the material it avoids all liability of the leading end of the wire not finding its way properly into the concavity of the anvil. The opposing jaw 2 has its nose 2 shaped to bear upon the upper b opposite the anvil 1 close in under the bottom of the last as indicated in Fig. 3, etc. In practice, the upper and the lip of the insole (or the upper and the margin of a sole in the case of a stitch-down shoe) being between the jaws as in Fig. 2, with the jaw 1 pressed home into the angle between the insole and its lip or flange, (or against the under surface of the sole in the case of a stitch-down shoe), the operation of closing the jaws together causes the outer face of the jaw 2 to wipe against the upper at the edge of the last, pressing the upper smoothly into piace around the said edge and into proximity to the shoulder of the insole, (or the upper surface of the sole.) The upper is held securely in place between the closed jaws while the wire is fed and driven through the portions of upper and lip (or sole) which are in the pinch of the jaws, and also while the wire is clenched and cut and the standing end of the inserted and severed fastening is bent over and the fastening finally set. By driving the fastening right at the pinch, it holds the upper where the latter is drawn by the jaw 2 in closing against the jaw 1.

The jaw 2 is formed at its back with a groove 3 which constitutes a passageway for the continuous wire (Z of which the fastenings are formed. The lower end of such groove opens through the nose of the said jaw, i. 6., the portion of the jaw 2 which coacts with the anvil jaw 1 in pinching the upper and the lip of the insole (or margin of the sole). At the upper end of the said groove a strip of metal 4 is made fast to the top of jaw 2 by means of a screw 5, such strip having an eye 4* in line with the groove, and also having a tongue 4 which extends downward, with the lower portion of its length within the groove. The wire passes through the said eye into the groove, and along the latter. The eye directs the wire into the groove, and the tongue holds the wire against the back wall of the groove below the eye. The said tongue acts, by its pressure against the wire, and through its frictional engagement with the latter, as a kind of tension-device. It holds the wire in place while the tool is not in engagement with the wire, and obviates accidental forward movement or accidental withdrawal of the wire at the time when the tool is out of contact with the wire. In the nose of jaw 2, the side-walls of the groove 3 converge as shown in Figs. 7, 8 and 9 at 3 to provide a centering guide for the wire, by means of which the wire is positioned accurately in the work in being driven.

At 6 is the tool by which the feeding, driving, cutting, etc., operations are performed. Its working portion 6" is reduced in width and enters into the groove 3. Such portion is beveled off above to form a cutting end at the lower corner thereof. The said tool has relative movements which cause its working end to move inward toward the back wall of the groove 3 and along the groove toward the nose of the jaw 2, then outwardly from the said back wall,

and then in the reverse direction len thwise of the groove to the starting point. he inward movement of the tool causes its working end to engage the wire, press it against the back wall of the groove, and cut part Way into and through the wire. As long as the engagement of the tool with the wire continues the wire cannot become displaced or withdrawn accidentally, and must accompany the tool in movement of the latter toward the stock into which the wire is to be driven. The movement of the tool toward the nose of the jaw 2, operates, by reason of the engagement of its working end with the wire, (1) to feed the wire lengthwise toward the material which is pinched between the jaws 1 and 2, (2) to drive the leading portion of the wire through the said material, and (3) to clench the end of the wire by forcing, it into the concavity of the anvil.

The cutting by which the portion of wire that has been inserted into the material or work is severed to constitute a fastening takes place as soon as the driving and clenching have been effected, but before the termination of the movement of the tool toward the material or work. The cutting is effected at a sufficient distance from the upper surface of the material or work to leave a projecting standing end of the partially formed fastening. The withdrawing or retracting movement of the tool relative to the wall against which it cuts takes place during the final portion of the approach of the tool toward the anvil, it beginning as s on as the cutting has been accomplished; The tool. bv reason of its combined onward and withdrawing movement keeps hold of the top of the standing end. which is relativelv long and if not controlled is liable to bend in any direction, and pulls the said standing end forward. at the same time that it crowds it toward the material or work. Thereby it bends the said standing end in the direction of the withdrawal of the tool, and in doing so it directs and controls the bending. As it completes the bending the pressure of the tool effects the final setting of the fastening. The return movement of the tool lengthwise of the groove replaces it at the starting point. The tool 6 is combined with a movable carrier 7.

In the present instance the jaws 1 and 2, and the tool-carrier 7, are mounted or hung upon the same pivotal pin 8. The stock 1 of the jaw 1 is fixed between the forward ends of the side-arms 9, 9, of a lever 9, which in this instance is extended rearward in the form of a handle. The said pivotal pin 8 is fitted to holes in the said side-arms. The jaw 2 is provided with side-arms 2, 2, which fit between the side-arms 9", 9 of lever 9, and are pivotally mounted upon the pin 8. Normally the jaws 1 and 2 are caused by means of a spring to stand apart from each other as is explained hereinafter. In being closed together, the jaw 2 is actuated by yielding force, one convenient means of applying such force being explained hereinafter. The tool'carrier 7 is pivotally mounted upon the pin 8 between the sidearms 2, 2, of the jaw 2. To provide for the actuation of the tool-carrier 7, a lever 10 is provided, it having side-arms 1O which are pivotally mounted upon the pin 8 intermediate the side-arms 2, 2 of the jaw 2 and the side-arms 9 9", of lever 9, the said lever 10 being extended rearward in the form of a handle, and the said side-arms 10 thereof being engaged with the tool-carrier 7 by means of screws 10", the stems of which latter work in curved slots 2, 2, made in the side-arms 2", 2, of jaw 2.

Normally, the parts being open or separated as in Figs. 1 and 2, the upper jaw 2 is held in the depressed position relative to tool-carrier 7 and tool 6 which it occupies in such figures by the action of a suitable spring, here constituted for convenience by a contracting spiral spring 11. one end of which is engaged with a post 7 projecting rearward from the top of tool-carrier 7, the other end of the said spring being engaged with a pin 2 projecting from one of the side-arms 2 of jaw 2, such sidearm being extended rearwardly. In contracting, the

said spring swings the jaw downward around pin 8 until the upper end walls of slots 2 bring up against the stems of the screws 10 as in Figs. 1, 2 and 3. This is the normal relation. Aspring-arm 12, made fast to lever 9 and bearing against a pin 2 projecting from the rearwardly-extending side-arm 2 of the jaw 2, acts with a tendency to turn the lever 9 so as to separate the jaw 1 from the jaw 2 to the fullest extent permitted by post 7, which acts as a stop for the said lever 9. The two springs 11 and 12 therefore tend to keep the parts normally in the open position shown in Figs. 1

and 2.

When power is appliedtending to close the levers together, the spring-arm 12 yields first, being weaker than spring 11, and relative approach occurs of jaw 1 with respect to the jaw 2 and the tool-carrier, as in Fig. 3, without change in the relative position of the jaw 2 and tool 6 with respect to each other, until the two jaws bring up firmly upon the material between them, as in Fig. 3, or until the stock 1 of the jaw 1 brings up against the under edges of the side-arms 2, 2, of the jaw 2. Meanwhile the comparatively strong spring 11 acts to hold the jaw 2 inits relatively depressed position with respect to the tool-carrier and tool, with the upper end walls of the slots 2", 2 of the side-arms 2, 2, of said jaw 2 pressed against the stems of the screws 10". Hence the jaw 2 is thereby caused to swing in unison with the tool-carrier 7 around the axis of pin 8, and to the same extent as the toolcarrier. until the closing of the jaws together is checked. When the said closing is checked and jaw 2 is prevented thereby from moving further in unison with the tool-carrier 7, the latter in completing its movement toward the jaw 1 moves independently of the jaw 2, as illustrated in Figs. 4, 5, 6. This independent movement of tool-carrier 7 causes the tool to feed the wire cl along toward the nose of jaw 2, and to drive the leading end of the wire through the material. It also causes the tool to effect the clenching, bending, and setting.

The stock of the tool 6, in the present instance, is fitted to a guideway in the toolcarrier 7 with capacity to move inward and outward relative to the rear wire-guiding wall of the groove 3. It is controlled and actuated by means of a toggle comprising links 14, 15. The link 14 has one end thereof connected pivotally at 16 to one end of the link 15, the other end of the latter being pivoted to an abutment-arm 17 which is carried bv lever 10. When the two links are substantially in line, as in Figs. 1, 2, 3, 4, the working end of the tool 6 stands projected from the tool-carrierclose to the back wall of the groove 3, and in engagement with the wire d. When the toggle-joint is bent, broken, or flexed. the tool is retracted from said wall as in Fig. 6. The alternate straightening and bending of the toggle are brought about through the action of pins 18 and 19, carried by the extended side-arm 2 of jaw 2, upon the links 14 and 15. The said side-arm 2 with its pins 18, 19,.constitutes a toggle-controller. In Figs. 1 and 2, in which the jaws are opened apart, and in Fig. 3, in which the jaws have been approached to each other but the feeding movement of the wire has not been commenced, the pin 18 is in contact with the under side of the links, and the toggle-joint is thereby held substantially straight, but with the pivot 16 just a little above the straight line joining the points of pivotal connection with the t ol and the abutmentarm 17, and with the working end of the tool projected into engagement with the wire as aforesaid. The toggle-joint is arranged to pass thus slightly beyond the said straight line so as to prevent accidental breaking or flexing of the joint by the back thrust of the tool as it cuts the wire d near the completion'of the feeding movement of the tool. A stop-pin 15 carried by link 15 and engaged by a prolongation of link 14 determines the extent to which the pivot 16 passes beyond the said straight line. In Fig. 4:, in which the parts are closer together than in Fig. 3, and in which the ceding has terminated and the wire has been cut, leaving a projecting standing end, the pin 19 is in engagement with the top side of the links and is beginning to depress the pivot 16 so as to draw the tool rearward. At this stage the tool is continuing to approach the jaw 1. The effect of the said approach, and of the retraction of the tool by reason of the bending of the toggle, occurring at one and the same time, is to draw the upstanding end ofthe severed fastening in the direction in which the tool is retracting, thereby bending the said end over in the predetermined path until it is pressed fully down, and consummating the final setting of the fastening. In Fig. 6, in which the approach of the tool of the anvil has been completed and the fastening has been set, the toggle joint is bent or broken and the tool is fully retracted. As the parts open again from their closed position in Fig. 6, the pull of the spring 11 upon the rearwardly-projecting arm 2 of jaw 2 holds the jaw 2 down upon the material between the two jaws until, by the action of the said spring in contracting, the tool-carrier 7 and lever 10 have been moved reversely relative to the said jaw the distance permitted by the slots 2 This relative movement of the tool-carrier and the lever 10 causes the tool to rise relative to the said jaw 2 in a retracted position until the engagement between the links and the pin 18 restores the toggle to its straightened position as in Figs. 1 and 2. To prevent the tool from shaking or jarring forward prematurely, a frictionspring '24 is placed within a cavity of the tool-carrier and arranged so as to bear against the tool. The friction between the tool and the said spring, and between the tool and the lower side of the guideway therefor, restrains the tool from too free endwise movement. The operation of straightening the toggle moves the tool inward toward the back wall of the groove 3 again so as to bite against the wire.

The back wall of the groove 3 is slightly eccentric with relation to pivotal pin 8, so that the said wall and the path of the working end of the tool converge as the tool descends. The eccentricity of the said back wall is such as to leave about three-fourths of the diameter of the wire between the wall and the cutting end of the tool when the tool occupies the position in which it is shown in Figs. 2 and 3. In the descent of the tool the convergence of the said back wall toward the path of the said cutting end crowds the wire gradually against the working end of the tool until the wire is completely severed. In order to enable the path of the tool to be adjusted to a nicety with respect to the said back wall, the abutment-arm 17 is pivoted at 20 to the lever 10, and provided with an adjusting screw 21 which makes contact by one end thereof with the back of the lever. Said adjusting screw is furnished with a lock-nut 22 to prevent accidental loss of adjustment thereof. Adjustment of abutment-arm 17 in one direction by means of the adjusting screw will cause the tool to work closer to the said wall, and adjustment thereof in the other direction will correspondingly vary the closeness of approach of the tool to the wall.

In many instances, in the use of wire of medium and large gage the width of the groove 3 may be so proportioned to the diameter of the wire that the side walls of the groove serve as lateral guides for the wire. However, the wire cl preferably used by me in practice for lasting purposes, and which is so small in diameter and so soft that it is impracticable to drive the same by means of devices heretofore known without confining the same by closely-fitting inclosing guide-walls, is in fact so small that any driver small enough to follow the Wire within such guiding side walls is too frail to be practical. The problem is to guide the wire properly and at the same time provide for driving it by means of a tool sufliciently strong and stable to be practicable. My experimenting has shown me that if the wire be given an initial bend into a curved path corresponding to a segment of a circle, as

in Figs. 2, 3, 4 and 6, conforming to a con-- cave inner guide-wall curved to constitute such segment, as in the said figures, it can be driven without being further guided. It will seek the concave surface of the said wall or supporting surface, and pressure on the end of the wire sufiicient to drive it compels the wire to seek escape in the direction already indicated by the curve of the sustaining wall, and it will not tend to cripple laterally. That is to say, being given an initial bend it seeks no other during the driving. It will be confined in the plane of the driver, between and by means of the driver and the said concave wall. The said concave wall constitutes a concave curvilinear wire-guide which is tangential to the line in which the wire is driven into the work. As closelyfitting side-guides are not required, I am enabled to secure satisfactory results with a groove 3 considerably wider than the diameter of the wire. This obviates all necessity for employment of a driving tool having an excessively thin and frail acting portion to work in the groove 3, and enables me to employ a tool having a working end of substantial thickness and corresponding strength.

From the foregoing description it will be apparent that in the illustrated embodiment of the invention the tool, jaw 2, and wire, have a common movement toward the stock into which a fastening is to be driven, until the said jaw reaches the stock, and thereaf ter the tool and wire have a further movement which elfects the driving, etc. It also will be apparent that in such further movement the initial portion thereof effects the feeding, driving, and clenching, and the latter portion thereof effects the cutting, bending of the standing end, and setting.

The construction may bevaried in many respects without involving departure from the principles of the invention.

In combination, wire-guiding means having a longitudinally concave guide-surface against which the driven wire is flexed by resistance acting endwise at the leading end while being driven, causing the wire to assume a corresponding longitudinal curvature thereby obviating transverse buckling or exing, with a wire-centering guide by which the wire is positioned in the stock into which it is driven, and a driver.

37. In combination, wire-guiding means having a longitudinally concave guide-surface against which the driven wire rests while being driven, with a wire-centering guide at the delivery-end of said guide-surface, and a driver.

38. In combination, a driver, and a guide for the wire in being driven, the said guide having a longitudinally concave wall and the wire being confined in the plane of the driver between and by means of the driver and the said concave wall.

39. In combination, a driver, and a wire guide having a longitudinally concave curvilinear wire-supporting face which is tangential to the line in which the wire is driven into the work.

40. In combination, wire-guiding means having a wire-guiding surface, a tool con structed and combined to move in a path regularly converging with respect to said surface and by its movement in such path to feed and drive the wire to form an inserted fastening, the gradual approach of the cutting edge to the said surface causing the cutting of the wire during the continuance of the feeding and driving.

41. In combination, a moving tool formed to cut and drive, and wire-guiding'means having a wire-guiding surface regularly converging toward the path of thetool to effect the cutting.

42. In combination, wire-guiding means having a wire-guiding surface, a moving tool formed to cut and drive, said surface and the path of the tool converging and thereby causing the cutting to occur, and means for adjusting the relation between said surface and path.

43. In combination, wire-guiding means having a wire-guiding surface, a moving tool formed to cut and drive, said surface and the path of the tool converging and thereby causing the cutting to occur, and means for adjusting the path of movement of the tool and the approach of its cutting latter jaw, the tool, and a wire engaged by In testimony whereof I afiix my signature sahli1 tool, in ulnisonh towarlg thedstgck 1111:1111 in presence of two witnesses. suc jaw reac ms t e stoc an t erea ter 1 giving continued movement; to the tool and FLANK MERRICK' 5 thereby effecting feeding, driving, clench- Witnesses:
